Background: Despite well-established criteria for identifying the critical view of safety (CVS) during laparoscopic cholecystectomy, its impact on intraoperative decision-making among trainees is unclear.
Methods: General surgery interns (n = 10) viewed a training module on the CVS criteria and then independently reviewed 20 cholecystectomy videos lasting 1 min each edited at various points of CVS dissection to include examples of both adequate and inadequate dissections. Participants were asked to identify the following CVS criteria for each video-(1) clearance of fat from the hepatocystic triangle; (2) exposure of the cystic plate; and (3) two and only two structures entering the gallbladder-and then decide if the structures were safe to divide.
Objective: To evaluate whether incidental pathologic T3a (pT3a) upstaging after partial nephrectomy (PN) for clinical T1 disease results in inferior oncologic outcomes compared to pT1a-b disease.
Materials And Methods: Retrospective chart review was completed at the University of Michigan and Moffitt Cancer Center to identify patients undergoing PN for clinical T1 masses between 1995 and 2015. A total of 1955 patients were identified, of which 95 had pT3a upstaging.
Far from Standardized: Using Surgical Videos to Identify Variation in Technique for Laparoscopic Sleeve Gastrectomy.

Background: Video assessment is an emerging tool for understanding variation in surgical technique.
Methods: Representative videos of laparoscopic sleeve gastrectomy (LSG) were voluntarily submitted by 20 surgeons who participated in a statewide quality improvement collaborative. The amount of time required to complete the salient steps of the operation was measured and variations in the tasks performed during each step were captured.
Background: Certain patient demographics and histopathologic features are risk factors for papillary thyroid cancer (PTC) recurrence after initial treatment. Our objective was to determine whether very young age is associated with aggressive pathologic features in patients with PTC.
Materials And Methods: A retrospective analysis was performed for PTC patients who underwent surgical treatment at the University of Michigan between 2006 and 2012.
Objective: To report and analyze the outcomes of endoscopic inguinal lymph node dissection (E-ILND), inclusive of video endoscopic ILND (VEIL) and robotic-assisted ILND (RAIL) approaches, in the largest reported series to date.
Materials And Methods: We retrospectively identified men with penile cancer who underwent E-ILND. Nodal resection volume, perioperative parameters, and postoperative complications were assessed and analyzed.
